- Article 320(3) lists the matters on which the Union Public Service Commission (UPSC) shall be consulted. - Clause (a) requires consultation on methods of recruitment (Statement A). - Clause (c) requires consultation on disciplinary matters affecting a person serving under the Government of India or a State (Statements B and C). - Article 335 relates to the claims of Scheduled Castes and Scheduled Tribes being taken into consideration in making appointments, consistently with the maintenance of efficiency of administration. While UPSC is consulted on recruitment, promotions, and suitability (where efficiency is key), the overall policy or the general "manner" in which effect is given to Article 335 provisions (like deciding reservation percentages or the broad framework) is primarily a governmental decision and not necessarily a matter requiring mandatory consultation with the UPSC in its entirety. UPSC's consultation is usually on the application of these policies in specific recruitment/promotion processes affecting principles of appointment and efficiency. - Therefore, UPSC is not necessarily consulted on the broad 'manner' of giving effect to Article 335 provisions, although it is consulted on specific recruitment/disciplinary matters arising from its implementation.
